问题描述
我在 ASP.NET Web 应用程序中有一个 GridView
,我在其中每行添加了两个按钮:
I have a GridView
in a ASP.NET web application, in which I have added two buttons in each row:
<ItemTemplate>
<asp:Button ID="btnEdit" Text="Edit" runat="server" />
<asp:Button ID="btnDelete" Text="Delete" runat="server"/>
</ItemTemplate>
现在如何通过单击一行中的编辑按钮从 gridview 中获取行数据?
Now how I can get the row data from gridview simply by clicking an edit button in a row?
推荐答案
你也可以像这样使用按钮点击事件:
You can also use button click event like this:
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="Button1" runat="server" Text="Button"
OnClick="MyButtonClick" />
</ItemTemplate>
</asp:TemplateField>
protected void MyButtonClick(object sender, System.EventArgs e)
{
//Get the button that raised the event
Button btn = (Button)sender;
//Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}
或
你可以这样做来获取数据:
OR
You can do like this to get data:
void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple ButtonField column fields are used, use the
// CommandName property to determine which button was clicked.
if(e.CommandName=="Select")
{
// Convert the row index stored in the CommandArgument
// property to an Integer.
int index = Convert.ToInt32(e.CommandArgument);
// Get the last name of the selected author from the appropriate
// cell in the GridView control.
GridViewRow selectedRow = CustomersGridView.Rows[index];
}
}
和 gridview 中的 Button 应该有这样的命令并处理 rowcommand 事件:
and Button in gridview should have command like this and handle rowcommand event:
<asp:gridview id="CustomersGridView"
datasourceid="CustomersSqlDataSource"
autogeneratecolumns="false"
onrowcommand="CustomersGridView_RowCommand"
runat="server">
<columns>
<asp:buttonfield buttontype="Button"
commandname="Select"
headertext="Select Customer"
text="Select"/>
</columns>
</asp:gridview>
